i will do my best, as this is my first guide.
i started out to buy 2k gold.
when i recived my gold, i sent it to my alt, a lvl 1 bank, from that point on, just be paintence and start to read the chat, when people selling stuff, like ore,gems, etc.
usally some good offers come through, but 60% of them, are willing to take a lesser offer from you, after that, put the things on AH, remember to update your actioneer daily, when you are doing this.
another way is AH.
recently i purchased 5times Enchanting Formula: Lifestealing for 12g each, u can easily resell them, to a higher value.
i was also lucky to buy bone framed bracers for 250g and resold them for 500g, thats a 100% profil there.
so far, my 2k has grown to almost 4k, its a slow process and you need to spend at least 2hours everyday.
its not really a guide, just some good traiding tips.
enjoy buying and selling
